The LMS that became Codespaces
A learning platform built on real developer tools that taught 10,000+ students to code and inspired how the world learns to program.
How a Sunday meeting changed education forever
August 2013“A Sunday Meeting?!?!”
Nine months into Flatiron School's operation, with three concurrent cohorts each modifying the curriculum their own way, a small faculty met on a Sunday to brainstorm solutions.
The vision: systematic mechanisms to track changes while maintaining quality. The solution: a curriculum management system leveraging Git and GitHub as the foundation.
Let's charge $1000 a month
Board members expressed skepticism. Competitors charged far less. But online education buyers weren't seeking course access. They sought life-changing outcomes.
The medium is the message, the tool is the learning
Learn.co was built to create an immersive educational experience using actual developer tools rather than simulated ones. Students worked with real code, real challenges, real workflows.
The developer workflow
- 01Fork GitHub repository
- 02Clone locally
- 03Install dependencies
- 04Run test suite
- 05Solve the lab
- 06Commit solutions
- 07Push to GitHub fork
- 08Submit pull request
Test-driven learning
The curriculum implemented test-driven methodology where students made code functional by passing tests. Red for failing, green for passing.
The Lights
Visual indicators tracking lab progress. Using GitHub webhooks, the system monitored actions creating real-time feedback, like your code congratulating you.
Browser IDE
Around 2015, the team developed an integrated server-powered IDE accessible directly in browsers. Click "Open" and launch a fully-configured environment in under 2 seconds.
Many developers from this team later worked on GitHub Codespaces.

You can lead a horse to water...
While most online platforms struggle with single-digit completion, Learn.co achieved over 70% by separating curriculum from task completion tracking.
The checklist system
A checklist system broke every activity into simple tasks that could be monitored automatically.
Automated everything
Students only got credit when they actually did the task, verified through API integrations.
Coach dashboard
Templates for different phases of the student journey, from pre-enrollment through job search.
The LMS that became GitHub Codespaces
“The GitHub team was so impressed they hired half our engineering team to build Codespaces.”
The ripple effect
Learn.co's approach influenced how the industry thinks about developer education, online learning platforms, test-driven learning, and browser-based development environments.
- Real tools over simulations
- Social over isolated
- Automated accountability
- Outcomes over access
When students love a platform so much they make it permanent
You know you've built something special when students tattoo your logo on their bodies. These Learn.co graduates didn't just complete the program, they became part of the family forever.
You learn from people, not from content
Learning is inherently social. At Flatiron School, student-to-student education was magical. Learn.co was built to replicate this collaborative environment online.
“Replicate the campus, not the classroom”
Ask a Question
Students posed questions in real-time to the community. Questions piped into Slack, tagged by lesson, averaging hundreds of threads daily.
Study Groups
Hundreds formed weekly with ~4 attendees average. Instructor-led study groups replaced traditional lectures. Many-to-many instead of one-to-many.
Pair Programming
When two students accessed the same lab, the platform prompted pairing opportunities. Technology detected when group work made sense.
Blogging
Students received domains and GitHub Pages blogs for weekly assignments. Posts surfaced on relevant lessons. Asynchronous social learning.
